输电网缺乏对由常规发电厂的关闭引起的意外系统故障作出反应的操作灵活性，这要求未来的有源配电网参与输电系统支持，例如，提供辅助服务。因此，需要适当的控制策略来真实的实时地将配电网络集成到输电网的操作和控制系统中。本文提出了一种新的配电网控制方案，以调节输电和配电系统之间的有功和无功功率交换。通过这种方法，灵活的负载和分布式发电机的有功和无功功率的行为进行调整，以满足由叠加传输系统确定的要求，同时尊重当地的操作限制，如电压约束。该方法的适用性证明在时域仿真的中压配电网，其中包含多个分布式发电机和灵活的负载。
The lack of operational flexibility in the transmission grid to react to unexpected system failures caused by the shutdown of conventional power plants requires future active distribution networks to participate in transmission system support, e.g., providing ancillary services. Thus, the need for adequate control strategies to integrate distributions networks in the operation and control systems of transmission grids in real time rises. In this paper a novel distribution network control scheme to regulate the active and reactive power exchange between transmission and distribution system is presented. With this method, the active and reactive power behaviour of flexible loads and distributed generators is adjusted in order to fulfil the requirements as determined by the overlaying transmission system while local operational limits, like voltage constraints, are respected. The applicability of the approach is demonstrated in a time-domain simulation of a medium voltage distribution network which contains several distributed generators and flexible loads.
